Chemical Behaviour

In a paper communicated to the Society in 1897, the author drew attention to increase in electrical conductivity as a characteristic of photo-chemical action, and in a second communication in December of the same year, made the following statement—“It would appear that the chemical behaviour of the acids just mentioned (HNO3, HCl, H2SO4) depends in many of their reactions on whether their concentration is above or below that corresponding to their maximum electrolytic conductivity.”

Solutions Of Electrolytes

The physical properties of solutions of electrolytes in non-aqueous solvents have been investigated in the past by a number of workers, but until recently the work in this field has been characterised to some extent by lack of accuracy and of co-ordination. The need for accurate experimental work in this direction is clear when it is realised that modern theories of the behaviour of electrolytes in solution are based almost entirely on data obtained for solutions in water. It is probable that a more complete understanding of the nature of solutions can come only through experimental work extending over a range of solvents: the peculiar properties of water as a solvent have tended hitherto to obscure many of the fundamental difficulties of the problem by cloaking them in the garb of simplicity. The work which forms the substance of this paper was undertaken with a view to obtaining some systematic data for the electrical conductivity of dilute solutions of uni-univalent salts in a non-aqueous solvent, of an accuracy comparable with that of Kohlrausch and his co-workers in the case of aqueous solutions. The choice of methyl alcohol as a solvent was governed by the fact that it is most closely allied to water in type, and is experimentally well suited for such an investigation.

The Relationship

Although great advances have been made during the last thirty years in our knowledge of dilute solutions, there has been no corresponding advance in respect of concentrated solutions. This is primarily due to the fact that hitherto no simple and general relationship has been discovered between the conductivity and the concentration of concentrated solutions of electrolytes. Ostwald's law of dilution holds only for dilute solutions of weak electrolytes, and the formulæ of Rudolphi and Van T'Hoff are applicable only to dilute solutions of good electrolytes. It seems therefore important to inquire whether the difficulty may not be to some extent overcome by an alteration in the mode of representing the facts.

Solutions Of Electrolytes

In this paper the results of observations of the elevation of the boiling point of aqueous solutions of electrolytes are given, and a few results of observations of the depression of the freezing point, together with conductivity data obtained by observations of conductivity at about 99·4° and 0° Centigrade.
